FLEXIBLE SHIN GLE.

Application lked February 28, 1923. Serial No. 621,720.

To all 'whom t may concern:

Be it known that I, HUGH MAclNNns, a citizen of the United States,residing at Jersey City, county 'of Hudson, and State ot' New J ersey,have invented a certain new and useful Flexible Shingle, of which thefollowing is a specification.

T his invention is an improvement in flex ible shingles for roofngs andsidings, and the object is to retain the marginal portion of saidshingle from distortion or curling under the effect ot solar heat andexposure to the weather, as well as to facilitate the installation orlaying ofthe shingle.

The article is of a composite character, usually comprising a basecomposed 0In f1- brous material, such as felt, which is waterproofed byimpregnating the same with an appropriate agent, like a low melt pointasphaltum, and the weather surface of said material is provided withcoatingsA one of which is usually a high melt point a .ttum, and theother is composed of granular material incorporated willi the lastnientioned-coating of i tuut Vl/'hsn installed on a roof, the `ingle,composed of materials such as described, is usually free or unrestrainedat the margins and it is exposed to heat and moisture, with the resultthat said free margins will become distorted and curl upwardly, exposing(he shingle to wind pressure admitted below said curled up edges, aswell as to theentry olf rain.

Heretofore it has been proposed to confine the lower exposed corner of aflexible shingle by providing said lower corner with an. underlying flapYformed by folding the lower corner under the shingle body, and byrestoring to the use of a mechanical fastener, such as a pin, attachedto the flap and projecting at its ends beyond the respectiveside edgesof the shingle- W'hcn installingy shingles provided with the underfolded corner flap and with theinetallic fastener, the workman isrequired Ato pull up the in; dividual shingle in order to position it inthe required relation to other shingles,I and this pulling up operationunfolds or "un ravels the flap, more or less, so that the metallicfastener will work loose in a wind storm, and when said flap becomesunfolded, or unraveled, even slightly, the head lap ot the shingle isdecreased. with the resulttthat the shingle is not safely applied toexclude rain and wind from beating under the shingle at the side andlower margin thereof.

l. have simplified the shingle construction hy omitting the flapaltogether, and in this invention the lower corner of the shingle is cntoil at an :ingle to the two side edges, the lower cut of? edge beingstraight. A metallie fastener' is used for retaining `the straightflapless edge of the shingle,.said fastener being a bar, pin or rodattached directly to the shingle body, adjacent the straight lower edgethereof, and with the ends portruding beyond the respective side edgesof the shingle.

Theomission of the flap attains economy in the manufacture of theshingle, both as to material used and the time and labor required tofold the flap; but. the straight lower edge allords a line definitelypredetermined in whichi the metallic fastener is appliedl The attachment0f the metallic fastener directly to the body of the shingle affords apermanent location fox-said fastener in lieu of a movable or shiftablerelation of the fastener to the shingle such as is afforded by theattachment of the fastener to the folded flap of prior shingles.

Other functions and advantages of 'the'inrention will appear from thefollowing .description taken in connection with the drawings, wherein-Figure l is a View showing a number of shingles applied in accordancewith my invention.

The shingle A. is a dat piece of material, substantially square inshape, andcomposefl of a basic layer of material, such4 as felt,

which in the process of making said shingle, i

is waterproofed by impregnating said layer with a waterproofing agent,such as a low melt point asphalt maintained in a hot Semiliquidcondition and within which bath the felt layer is conducted. To theweather surface of the material, is applied two coatings, one composedof a high melt point asphalt and the other of granular material. Thesurface coating resists the effects of solar heat, and the granularmaterial is* pressed into the surface coating so as to become intimatelyincorporated therewith. The materiel is prepared economically in sheetforno, and the square shingles A are cut by appropriate mechanism. fromsaid shingles.- The fastener pin or rod of the sheet. v overlyingshingle fits beneath the edges of The shingle is devoid of a flap, orany elethe shingles below and acts as a retainer in ment resembling saidflap, or any equivalent confining the lower corner and the marginstherefor.
